What can we say, an inexperienced referee in a semi-final, could we expect more? I think that Orosco did not do brilliantly, but without any doubt, it was certainly no total failure in a normal match where he failed in some basics but without bigger errors, taking everything into consideration, we can say that Orosco showed a decent perfomance.

Red Card (s)
We can say that the two dismissals are the keys of the match, one given and another not, first the red card of Juan Vargas, a very clear elbow in the face of the Uruguayan player, Orosco was close to the action and did not hesitate to show him the straight red card (unbelievable that CONMEBOL merely suspends him for one match!).
The other one should have went against Lugano who commited many fouls without having been cautioned, that many that he should have been sent off due to two yellows or directly when Orosco showed him first the yellow card. Furthermore, he had problems with his positioning on the pitch and he did not solve exaggerated protests in an adequate way.
